Moving Apps to External Storage in Samsung Galaxy Tab


After updating the Samsung Galaxy Tab2 to JellyBean, I realized that it is no longer possible to move the applications to external storage.

Application like 'App2SD' is giving the error message -
"the device does not have a real primary external storage, or the primary external storage is emulated"

The reason is -Android removed the support for moving the apps to external storage in the newer releases of the OS! So if you are using a device with Android version later than 3.0 then moving apps to SD card is not possible.
There is no easy and reliable app or workaround which will help you to do this.

There are different theories why this happened -

  1. Google in general trying to kill SD cards.
    1. Remember, google devices like Nexus does not support external storage.
  2. Any thing to do with the Patent issues with Microsoft?
    1. Android is said to be the most successful mobile operating system of Microsoft, as Microsoft gets $$ for each Android phone sold. 
Read about Google's explanation for the lack of SD card support in Nexus devices here

May be the basic users will not even notice the lack of SD card support, But this IS a disadvantage for the advanced users. With the new games increasing in size it will be pain to decide which ones to uninstall before installing a new one.

Looks like experts at Google are telling that 8Gb/16Gb in a mobile device is enough for any one.
I hope they will remember another famous quote by Bill Gates 
"640K ought to be enough for anybody "
